当我在Android 4.4及更高版本上运行时,我正在我的应用中使用沉浸式模式.(http://developer.android.com/training/system-ui/immersive.html)

我的活动确实以全屏显示,我通过使用按下音量键setOnSystemUiVisibilityChangeListener.我也有类似的代码将对话框放入沉浸式模式.

但是,当显示对话框时,导航.酒吧跳到屏幕上,然后立即撤退.当对话被解雇时,情况更糟 - 导航.酒吧跳跃并调整背后的活动.

以下是我的支持沉浸式模式的课程.它只是在每个Activity的onResume上调用,并且在构建每个对话框时也会调用一个单独的函数.

我错过了任何旗帜或回调,还是已知的Android问题？

public class ImmersiveModeHelper {

    public ImmersiveModeHelper(Activity activity)
    {
        mActivity = activity;
    }

    @SuppressLint("NewApi")
    public void supportFullScreenImmersiveMode()
    {
        MyLog.d("ImmersiveModeHelper: supportFullScreenImmersiveMode: ");

        // Support full-screen immersive mode on Android 4.4 and up
        if (Build.VERSION.SDK_INT >= 19)
        {
            // Get the needed flags by reflection and use them
            try
            {
                final int immersiveFlag = View.class.getField("SYSTEM_UI_FLAG_IMMERSIVE_STICKY")
                        .getInt(null);
                final int hideNavigationFlag = View.class
                        .getField("SYSTEM_UI_FLAG_HIDE_NAVIGATION").getInt(null);
                final int fullScreenFlag = View.class.getField("SYSTEM_UI_FLAG_FULLSCREEN").getInt(
                        null);
